Description

  The present invention relates to absorbent articles such as sanitary napkins, panty liners (clays, urinary leakage care liners), incontinence pads, interlabial pads and the like provided with disposal means.

  A conventional sanitary napkin that can be folded and rolled up for disposal after use and can self-seal, (a) two ends, two long edges, underwear A long central absorbent element having a side facing the body and a side facing the body, (b) a backing layer substantially covering the body facing side of the absorbent element, (c) a long edge of the backing layer At least one flap extending transversely at one end thereof, and (d) the napkin is wound or folded about a transverse axis to be discarded, and the flap is said wound or folded napkin A sanitary napkin comprising first adhesive means placed in place on the backing layer to bond the flap to the backing layer when wrapped around (Patent Document 1: Japanese Patent No. 2688359).

  However, in such sanitary napkins, when discarded, the napkin is wound or folded around the horizontal axis, and when the flap formed on the napkin is wound around the wound or folded napkin, In order to adhere the flap to the back sheet side, an adhesive means is provided at a predetermined position on the back sheet. Therefore, the original function as a napkin (fixing to underwear to prevent twisting and slipping) is greatly impaired. Hereinafter, it demonstrates concretely using drawing.

  FIG. 1 shows a state in which a general flap napkin 1 is fastened to an undergarment 6, FIG. 2 (A) shows a back side of a general flap napkin, and FIG. The back of the napkin is shown. Referring to FIGS. 1 and 2A, when used, a fastening portion 4 formed on the backsheet surface 2 of the napkin 1 and a fastening portion 4 ′ formed on a flap 3 extending from the backsheet surface 2 are used. The napkin 1 is fastened to the underwear 6 via In this general napkin 1 with a flap, when the napkin receives the external pressure (side pressure) during use, the napkin is most likely to be bent or misaligned, or the part where the napkin is fastened to the underwear. A flap 3 and a fastening portion 4 ′ are formed at a short portion (crotch narrowest portion) 7 so as to fasten the crotch 7 so as to be wound around. However, in the napkin 1 ′ shown in FIG. 2 (B), the napkin 1 ′ is disposed of so that the napkin is not opened by the flap 3 ′ after being wound or folded around the horizontal axis of the napkin. It is supposed to do. Therefore, the flap 3 ′ is folded on the backsheet 2 during use, and the fastening portion 4 ″ is formed on the flap 3 ′ folded on the backsheet 2. 'And the fastening part 4 "are structures that cannot be fastened as a crotch is wound, and the napkin in FIG. 2 (B) has the same structure as a non-flap napkin in terms of slippage prevention during use. Sure and misalignment are likely to occur.

  Further, FIG. 3A shows the back side of a general napkin without a flap, and FIG. 3B shows the back side of a napkin taught in Patent Document 1. In both cases, the napkin 1 ′, 1 ″ is used in use. The napkin is fastened to the underwear by the fastening part 4 or the fastening parts 4, 4 ″ formed on the backsheet surface 2 of the back sheet. The flap-less napkin 1 "is fastened with a crotch wrapped around it, and since there is no flap that is highly effective in shifting, the flap and the napkin 1 are not compared with the flap napkin 1 shown in Fig. 2 (A). However, the structure of Patent Document 1 is more likely to be distorted and displaced than a conventional napkin without a flap because the napkin body 1 'and the underwear are directly fastened. This is because the area of the fastening parts 4 and 4 ″ is divided into the back sheet surface 2 and the flap 3 ′, which is smaller than the area of the fastening part 4 of the napkin 1 ″ without the flap. In this structure, the fastening portion 4 ″ is formed on the flap 3 ′, but the flap 3 ′ is only folded on the back sheet 2 and is separated from the napkin body 1 ′. The flat 3 'only is fastened to the undergarment 6, the napkin body 1' so is in the state of being separated from the undergarment 6, twisting, misalignment is more easily generated.

  An absorbent article (a sanitary napkin) according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 4: is the top view which looked at the sanitary napkin which is the absorbent article of embodiment of this invention from the back surface sheet side, XX direction, and sectional drawing of a YY direction. FIG. 5: is the top view which looked at the sanitary napkin which is an absorptive article of another embodiment of this invention from the back sheet | seat side, sectional drawing of XX direction and YY direction.

  4 and 5, the sanitary napkin 11 includes a liquid-permeable top sheet 12, a liquid-impermeable back sheet 13, and an absorbent body 14 interposed therebetween, and is formed substantially vertically long. ing. The top sheet 12 and the back sheet 13 are joined at both longitudinal ends of the sanitary napkin 11. Left and right side edges of the top sheet 12 and the back sheet 13 extend outward, and flaps (also referred to as wings for sanitary napkins; hereinafter referred to as wings) 15 and 15 are formed. As a material for forming the top sheet 12 and the back sheet 13, generally known materials can be used without particular limitation.

  The length of the napkin 11 (napkin body 19) may be various sizes, but is generally 170 to 420 mm (more preferably 200 to 360 mm). The width of the napkin main body 19 (particularly the absorbent body 14) is preferably 150 to 200 mm (more preferably 165 to 185 mm) since the width of the crotch portion of the underwear is 60 to 90 mm (or 50 to 100 mm). When the napkin main body 19 or the absorbent body 14 is configured, the dimensions of the crotch portion of the underwear are important from the viewpoint of absorption performance, leakage prevention, and mounting performance.

  In the present invention, the napkin area (“crotch-compatible area”) 7 ′ corresponding to the crotch in the present invention is located near the center of the napkin body 19 in the longitudinal direction and corresponds to the crotch portion of the underwear as shown in FIG. An area to be designated is designated. In the present invention, the wings 15 and 15 are formed in the crotch-corresponding region 7 ′, and at least a part of the wings 15 and 15 is in a region including the center in the longitudinal direction of the napkin body 19 (the napkin body 19 It is formed across the longitudinal center). The width of the wings 15 and 15 (length in the napkin length direction) is near the center of the wing length (length in the width direction of the napkin) (near the center of the length of only the wing not including the napkin body). The width is preferably 40 to 120 mm (more preferably 50 to 100 mm). The length of the wings 15 and 15 is preferably 25 to 40 mm (more preferably 30 to 35 mm).

  In any of the embodiments shown in FIGS. 4 to 10 of the present invention, a sheet (cover sheet 16) that covers the entire back sheet 13 is formed on the surface of the back sheet 13.

  Although it is preferable that the cover sheet 16 matches the back sheet 13 in terms of function and cost of the manufacturing process, it is not always necessary to match completely. For example, the cover sheet may have a shape that matches a napkin body that does not have a wing.

  It is preferable that the cover sheet 16 is bonded to the back sheet 13 at both ends in the longitudinal direction and both ends in the width direction in order to function so as to wrap the napkin body (longitudinal end joint 16a, width end joint). 16b).

  The cover sheet 16 is formed with a (completely) separated line (cutting line) 17 or a cutting auxiliary line 17 such as a perforation (hereinafter simply referred to as a line 17) at the center in the width direction. It is preferable that the line 17 is linearly formed from the front end portion in the longitudinal direction to the rear end portion in the longitudinal direction.

  In FIG. 4, the line 17 has the part (opening part) 17a extended in the product width direction regularly or irregularly so that the back surface sheet 13 can be seen with the cutting line 17 or the auxiliary cutting line 17. It is preferable that the spread of the opening portion 17a is 1.5 mm to 3 mm.

  4 and 5, the surface of the cover sheet 16 is integrated with a plurality of fastening portions 18, 18, 18a (adhesive elements for fastening to underwear during use, fastening portions 20, 20). Thus, the crotch part of the undergarment can be fastened so as to be wound in). In FIG. 4, in addition to the pair of left and right fastening parts 18, 18, a fastening part 18 a is also formed on the line 17. The planar shape of the fastening portions 18, 18, 18a is not necessarily limited, but a rectangular shape is simple. The size in the longitudinal direction of the fastening portions 18, 18, 18a is preferably the same as the size of the absorbent body 14, or shorter than that by 5 mm to 10 mm. The size of the fastening portions 18, 18, 18a in the width direction is not particularly limited, but is preferably 5 mm or more even if it is small. Generally, it is 10-30 mm, More preferably, it is 15-25 mm. The number of the fastening parts 18, 18, 18a is preferably at most a plurality, particularly 2 to 3 in consideration of fastening to a place where the length of the underwear is the smallest in the width direction (crotch narrowest part).

  4 and 5, the position of the fastening portion 18 in the napkin width direction is such that the distance from the center portion in the width direction of the napkin main body 19 toward the left and right outer sides to the innermost edge of each fastening portion, It is preferable to be within the range of 30 mm or less (more preferably 15 to 40 mm).

  When the back sheet 13 and the cover sheet 16 are joined only at the edges by heat embossing, ultrasonic waves, hot-melt adhesive alone, or a combination of these, the underwear and the fastening are in use. Only the cover sheet 16 is provided, and the napkin main body 19 is close to a state where it is only placed on the cover sheet 16 and is not fixed to the underwear at all. As a result, an external force is easily applied to the product body of the sanitary napkin 11 as a result of the external force being applied, and as a result, there is a possibility that a twist or a deviation may easily occur. In order to prevent this from happening, the narrowest part of the crotch, in part, especially at the place where the sanitary napkin 11 is subjected to the most external force during use and the sanitary napkin 11 is prone to misalignment or to be attached to the undergarment. It is desirable that the portion to be attached to the underwear is directly attached to the underwear. Therefore, as shown in FIG. 4, since the wing is formed at least in the crotch portion (the crotch portion (crotch-corresponding region) in the typical napkin of the present invention), the crotch portion in the napkin of the present invention has the wing-corresponding region (flap). The line 17 is provided with a portion 17a extending 1.5 mm to 3 mm in the product width direction so that the back sheet 13 can be seen, and a fastening portion 18a is formed in the expanded portion 17a. It is preferable.

  Since it is desirable that the cover sheet 16 and the back sheet 13 are also adhered, it is desirable that the size of the fastening portion 18a in the width direction is also 5 mm or more at a minimum. If the line 17a extends 3mm or more, the area that can be fastened to the underwear also increases and it becomes easier to suppress twisting and shifting, but at the time of disposal, it is disposed on the surface of the absorbent article in a discarded state through the opening 17a. Since the problem that the adhesion of the fastening part arranged on the sheet side appears remarkably occurs, it is desirable that the sheet does not spread more than 3 mm. At this time, it is desirable that the coating thickness of the fastening portion 18a be as thick as it can be applied from the surface of the cover sheet 16 and applied to the back sheet 13.

  However, in the present invention, it is not essential to form the portion (opening portion) 17a where the line 17 spreads and the fastening portion 18a thereon. Moreover, the line 17 should just be made to be easy to tear a cover sheet | seat in a product width direction, and the line may be a simple straight line or a curve, and may specifically be cutting auxiliary lines, such as a perforation. It is also optional to provide a fastening portion 18a that covers the line 17.

  FIG. 5 shows an example of a mode in which the line 17 is a straight perforation without the opening 17a and the fastening part 18a on the line 17 is not present.

  4-6, the cover sheet 16 of the wings 15 and 15 is fixed to the surface of the fastening parts 20 and 20 (the crotch part is wound around the underwear together with the fastening parts 18 and 18a when used). And an adhesive element for fastening. In the absorbent article (sanitary napkin), the fastening parts 18, 18, 18a and the fastening parts 20, 20 are protected by a release paper or a release film 22, 23 (FIGS. 6A and 6C). reference).

  As the material for forming the cover sheet 16, the fastening parts 18, 18, 18 a and the fastening parts 20, 20, generally known materials can be used without particular limitation as with the top sheet 12 and the back sheet 13.

  The cover sheet 16 preferably has a total light transmittance of 20 to 60% or less. The cover sheet is overlapped in a top sheet shape at the time of disposal, and it is necessary to visually conceal excrement. Therefore, concealment of excrement can be achieved by setting the light transmittance to 60% or less, more preferably 50% or less. On the other hand, when the cover sheet is configured to be smaller than 20%, the flexibility of the sheet tends to be impaired, which is not preferable as an article to be worn along the body.

The total light transmittance is a ratio (percentage) of the amount of light after transmission to the amount of light before transmission of visible light transmitted through the cover sheet, and can be measured by a known method. Specifically, it can be performed by the following measuring method.
Measurement of total light transmittance: Measurement was carried out in accordance with the standard of JIS-K7105. Measurement was performed using a color difference meter (Nippon Denshoku Industries Co., Ltd. Kyotsutsu Photometric Color Difference Meter Z-300A).
Specifically, a sample having a width of 5 mm and a length of 5 mm was sandwiched between turbidimeters to obtain a TT value.
The TT value was recorded as the total light transmittance (%), 10 samples were measured in this measurement, and the average value was taken as the light transmittance.

  As the surface sheet 12, a perforated or non-porous nonwoven fabric or a porous plastic sheet can be used.

  As the back sheet 13, a hydrophobic nonwoven fabric, a water-impermeable plastic film, a laminate sheet of a nonwoven fabric and a water-impermeable plastic film, or the like can be used. Further, it may be an SMS nonwoven fabric sandwiched between a melt-blown nonwoven fabric having high water resistance or a strong spunbond nonwoven fabric.

  The absorbent body 14 can be made of fluffy pulp or an airlaid nonwoven fabric, but can also contain a superabsorbent polymer. Examples of the fluffy pulp include artificial cellulose fibers such as chemical pulp, cellulose fibers, rayon and acetate. As an airlaid nonwoven fabric, there is a nonwoven fabric in which pulp and synthetic fiber are heat-sealed or fixed with a binder. Examples of the superabsorbent polymer include starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers.

  As described above, the cover sheet 16 is most preferably a water-impermeable plastic film, but other materials similar to the back sheet 13 can also be used.

  In the fastening parts 18, 18a, 20, styrene-isoprene-styrene block copolymer (SIS) styrene-butadiene-styrene block copolymer (SBS), styrene-ethylene-butylene-ethylene copolymer (SEBS), etc. Hot-melt pressure-sensitive adhesive or the like can be used.

  The edges 16a and 16b of the cover sheet 16 are made of heat embossing, ultrasonic waves, hot-melt adhesive or the like alone or in combination, and are joined to the back sheet 13.

  As will be described with reference to FIGS. 7 to 8, the cover sheet 16 is preferably joined to the napkin main body 19 so as not to be peeled off at the entire peripheral edge portions 16 a and 16 b. The cover sheet 16 can be turned upside down through the opening and the napkin body 19 can be wrapped.

  The joining strength between the cover sheet 16 and the napkin body 19 is preferably at least 4N. Although it depends on the type of underwear, the fastening strength between the fastening parts 18 and 20 and the underwear is usually 2 to 4 N, and the cover sheet can be used in the napkin when used by using a higher joining strength. It can prevent coming off from the main body.

  The bonding strength between the cover sheet and the absorbent article body can be measured as follows. First, a sample for measurement is cut out with a dimension of 25 mm in width in the article length direction of the absorbent article and 30 mm in length in the same width direction, including the joint portion. At this time, joints other than the joint to be measured are peeled off in advance. Next, using the tensile tester [Autograph AGS-50NX, manufactured by Shimadzu Corporation] with the direction along the length direction of the measurement sample as the measurement direction, fix the sample end to the chuck so that it can be peeled off. Then, the maximum load when peeling at 180 ° peel at a peeling speed of 100 mm / min is measured. Ten samples were measured, and the average value was taken as the bonding strength.

(Disposal method of sanitary napkin after use)
With reference to FIGS. 7 to 9, a method of disposing the sanitary napkin 11 whose surface on the surface sheet 12 side is soiled with menstrual blood or the like 25 after use is removed from the underwear will be described.

  In one preferred embodiment, as shown in Step A of FIG. 7, the wing 15 is folded back to the surface sheet 12 side that is contaminated with the menstrual blood 25 of the detached napkin 11, and the cover sheet and the napkin are interposed via the wing 15. Prepare to turn the unit upside down.

  Referring to Step B of FIG. 7, four fingers other than the thumbs of both hands are applied to the back sheet 13 side of the napkin 11 obtained in Step A, and each hand is placed near the fastening portions 18 and 18 on the back sheet 13 side. And the thumbs of both hands are attached to the fastening parts 20 and 20 of the wings 15 and 15 on the surface sheet 12 side.

  Specifically, as shown in Step B of FIG. 7, the fastening parts 18, 18 on the back sheet 13 side with the thumb attached to the fastening parts 20, 20 of the wings 15, 15 on the top sheet 12 side. Move the left and right cover sheets 16R and 16L to the left and right using the four fingers adhered to each other, cut off the cover sheet 16 along the line 17, and move the four fingers on the back sheet 13 side further to the left and right to cover The sheets 16R and 16L are opened on both sides.

  Hereinafter, description will be made with reference to FIG. 8, but the depiction of the hand shown in Step B of FIG. 7 is omitted in FIG. 8. Step C in FIG. 8 shows the back sheet 13 side in which the cover sheets 16R and 16L are slightly spread left and right with the four fingers of both hands shown in Step B. The cover sheet 16 is joined to the napkin main body 19 at the entire periphery thereof. When the opening (line 17) in the center of the cover sheet 16 (16R, 16L) is opened, the napkin main body 19 and the cover sheet 16 open the opening. A bag having (line 17) is formed. Step C in FIG. 8 shows the state of the bag. When the bag is turned upside down using the opening (line 17), the top sheet 12 side can be completely accommodated in the turned up bag.

  Step D in FIG. 8 represents a state in which the cover sheets 16R and 16L are further spread left and right from Step C with four fingers of both hands from the surface sheet 12 side of the napkin 11. The cover sheets 16R and 16L are spread to the left and right with the four fingers of both hands and wider than the width of the napkin main body 19, and the surface sheet 12 side of the napkin main body 19 is pushed into the back side with the thumb and becomes slightly narrower. The state of being is drawn.

  Referring to Step E of FIG. 8, after spreading the cover sheets 16R, 16L with four fingers of both hands, the cover sheets 16R, 16L are further wrapped so that the cover sheets 16R, 16L wrap the surface sheet 12 side of the napkin body 19. At the same time, the top sheet 12 side of the napkin body 19 is pushed into the folded cover sheets 16R and 16L. As described above, since the cover sheet 16 and the napkin body 19 form a bag-like object having an opening (line 17), the bag-like object is turned over using the opening (line 17). The top sheet 12 side can be completely accommodated in the bag-like product turned upside down, and the diagram of step E in FIG. 8 is the inside-out formed by the cover sheets 16R and 16L thus folded. The state in which the surface sheet 12 side which has the dirt 25 of the napkin main body 19 is pushed in is shown.

  Further, as shown in Step F of FIG. 8, after the surface sheet 12 side of the napkin body 19 is pushed into the folded cover sheets 16R and 16L, the fastening portions 20 and 20 of the cover sheets 16R and 16L are used. Then, the left and right cover sheets 16R and 16L are bonded together.

  The cover sheets 16R and 16L are covered so that the top sheet 12 cannot be completely seen. Since the surface sheet 12 after use will be exposed if it only coat | covers with the cover sheets 16R and 16L, the fastening part 18a (18) will be adhere | attached. By doing so, the surface sheet 12 after use is not exposed even if some external force is applied.

  A fastening portion 18 a is formed on the back sheet 13 at a portion (opening portion) 17 a that regularly or irregularly spreads in the product width direction so that the back sheet 13 on the line 17 of the cover sheet 16 can be seen. In the disposal method and disposal form as described above, the fastening portion 18a is exposed, but the spread is 1.5 mm to 3 mm, and the fastening portion that is most securely fastened to the underwear Since it is 18a, when the sanitary napkin 11 is peeled off from the underwear for disposal, the fastening portion 18a is in a state where the fibers of the underwear are also bonded, and the fastening strength is greatly reduced. Therefore, it is possible to prevent the fastening portion 18a from adhering to the finger and being unable to be disposed of well in the sanitary box for disposal or sticking in the sanitary box and becoming difficult to remove. .

  Thus, according to the napkin of the present invention, it is possible to wrap the napkin with the cover sheet and discard it without touching the dirt 25 such as menstrual blood on the top sheet 12.

  In the above description with reference to FIGS. 7 to 8, the hole 17 a and the fastening part 18 a exist in the line 17, but when there is no hole 17 a and the fastening part 18 a, the same processing as above is performed. It is possible to discard the napkin.

  Moreover, in the napkin disposal method of said process A-F, since the junction part of the whole peripheral part of the cover sheet 16 is not peeled off, it comprises the bag-like thing, The cover sheet 16 of the bag-like thing is attached. By turning over, the napkin main body 19 is wrapped in the cover sheet 16, but the joint 16 a at the longitudinal end of the cover sheet 16 may be peeled off and the napkin main body 19 may be wrapped using the cover sheet 16. .

  Referring to FIG. 9, this embodiment is similar to the example of the napkin of FIG. 5, but when the line 17 is a cut line, the cover sheet is pulled from both sides along the cut line. 16 (16R, 16L) is opened along the line 17. When the line 17 is opened from the beginning, the opened cut (line 17) is used as it is.

  Prior to this, it is preferable to fold the wings 15 and 15 to the top sheet 12 side as in step A of FIG.

  Referring to Step C ′ in FIG. 9, when a force for pulling the cover sheets 16R and 16L on the left and right sides of the opened line 17 shown in FIG. 5 is applied to the left and right, the joint 16a (cover sheet at the front and rear ends of the napkin body 19 is applied. 16 and the back sheet 13 are peeled off, and the cover sheets 16R and 16L can be opened to the left and right and folded back to the back sheet 13 side. At this time, the bonding 16a is preferably bonded, but, for example, even if it is heat embossing or the like, the bonding can be peeled off if the bonding is performed at intervals.

  Cover sheet 12 is covered using cover sheets 16R and 16L folded back to back sheet 13 side. At this time, if the napkin main body 19 is wrapped and joined so that the cover sheets 16R and 16L overlap with each other by using the displacement stoppers 18 of the cover sheets 16R and 16L, the hands become dirty with the dirt 25 on the napkin surface sheet side. This is avoided (step D ′ in FIG. 9).

  In the above steps, the order of the steps does not have to be the same as the order of the above description. For example, the wing 15 may be folded back to the top sheet 12 side after first cutting out the cut line of the line 17.

  As described above, according to the absorbent article of the present invention, the used surface sheet can be covered cleanly without touching the use surface, and can be reliably and quickly discarded.
